The tag implication #64985 inner_monologue -> thinking is pending approval.

Reason: Inner monologue is thinking with text

thinking wiki says:
When the character's expression denotes that it is thinking on something.

Not all instances of a character having an inner monologue has such an expression:

If the text and thought bubbles were removed, there's nothing about their expression to indicate they're thinking on something.

IMO that seems like a wiki issue... I think any instance of thinking should qualify for the thinking tag. If we want a tag for a thinking facial expression specifically, how about thoughtful or thoughtful_expression?
